Problems solved by technology
[0006] (1) The cam mechanism is noisy and easy to wear during the embroidery process
[0007] (2) The component that fixes the presser foot moves up and down for a long time and is easy to rotate, resulting in misalignment of the presser foot and needle bar and cannot be used together
[0008] (3) The transmission mechanism of the presser foot occupies the space inside the casing, so that the electromagnet assembly for clamping the upper thread needs to be installed away from the main shaft, and the working reliability is poor

The invention relates to the technical field of embroidery machines, and provides an independent presser foot transmission mechanism, wherein the presser foot drive shaft (7) passes through the casing (1) vertically, and the lower end of the presser foot drive shaft (7) is fixed to the presser foot The plate (5) is fixedly connected, the presser foot fixing plate (5) is fixedly connected to the presser foot (4), and the lower part of the presser foot driving shaft (7) is sleeved with a return spring (8); the upper end of the presser foot driving shaft (7) passes through the Over the lower plate (92) of the presser foot driving frame (9), the buffer spring (10), the connecting block (11), the upper plate (91) of the presser foot driving frame and the upper plate (91) of the presser foot driving frame 9 Fixedly connected, the buffer spring (10) is sleeved on the upper part of the presser foot drive shaft (7); the connecting block (11) is connected with the swing arm (15) through the connecting rod (13), and the swing arm (15) is connected with the transmission shaft ( 17) Fixed connection, one or more sets of driving components (18) are connected with the transmission shaft (17) and drive the transmission shaft to rotate. Independent presser foot transmission mechanism reduces spindle load, high embroidery precision and fast embroidery speed.
Description
technical field [0001] The invention relates to the technical field of embroidery machines, in particular to an independent presser foot transmission mechanism, an embroidery machine head transmission mechanism and a computerized embroidery machine. Background technique [0002] In the field of embroidery machine technology, automated computerized embroidery machines have replaced manual work. The computer embroidery machine has fast embroidery speed and high precision. In order to make computerized embroidery machines work more efficiently, practitioners in the field of embroidery machine technology are constantly working on how to improve the speed and accuracy of embroidery operations. [0003] Chinese patent application 201720868288.3 discloses a transmission structure for an independent presser foot on an embroidery machine. In this transmission structure, an auxiliary shaft is added to share the load of the main shaft and reduce the load on the main shaft. The main sh...
